Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148148, here are decompositions:
- 127 + 148021 = 148148
- 151 + 147997 = 148148
- 199 + 147949 = 148148
- 211 + 147937 = 148148
- 229 + 147919 = 148148
- 337 + 147811 = 148148
- 349 + 147799 = 148148
- 379 + 147769 = 148148
Showing the first eight; more decompositions exist.
